Jerry Snitselaar ff078d8fc6 tracing: Use seq_buf_used() in seq_buf_to_user() instead of len ...

commit 5ac4837841 ("tracing: Use trace_seq_used() and seq_buf_used()
instead of len") changed the tracing code to use trace_seq_used() and
seq_buf_used() instead of using the seq_buf len directly to avoid
overflow issues, but missed a spot in seq_buf_to_user() that makes use
of s->len.

Cleaned up the code a bit as well per suggestion of Steve Rostedt.
